CF488A phalloidin conjugate is the mushroom toxin phalloidin labeled with our superior green fluorescent dye CF488A. Because of their highly specific binding to F-actin, fluorescent phalloidin conjugates are excellent tools for cytoskeleton studies. CF488A is a superior alternative to the traditional green fluorescent dye FITC (or fluorescein) owing to its exceptional brightness and photostability. CF488A has brightness and photostability comparable to Alexa Fluor? 488.
